Today, the classical electronic computer architecture is one of the limiting factors for fast and energy-efficient data processing. This has triggered the search for alternative hardware architectures to overcome these limitations. For instance, neuromorphic photonics has emerged as a novel research field for new classes of information processing devices that incorporate photonically integrated neural networks [1].
The hybrid nature of surface plasmon polaritons (SPPs) offers a concept for integrating neuromorphic photonics by combining photonic advantages such as high bandwidth and speed with strong electronic interactions. Here, we present an experimental approach to constructing essential components of an artificial neuron based on SPP interactions. We optimized the dimensions of individual components through a combination of finite-difference time-domain (FDTD) simulations and iterative experimental adjustments. The resulting plasmonic responses are imaged using a photoemission electron microscope (PEEM).
